CULTIVATO R.

SPECIFICATION forming part of, Letters Patent`No. 251,976, dated January3, 1882.

Application tiled September 27, 1881.

To all whom Ait may concern Be it known that I, DANIEL C. VAN BEUNT, ofHoricon, in the county of Dodge, and in the State of VVisconsimhaveinventedcertain new and useful Improvementsin Gultivators; and I dohereby declare that the following is a t'ull, clear, and exactdescription thereof.

My invention relates to that class ol' culti vater-teeth that aredesigned to slip and give when they meet an obstruction that would `belikely to bend a tooth that was rigidly secured to its beam; and thenature of my invention will be fully set t'orth hereinafter.

In the drawings, Figure l is a perspective view of my device and asection of a cultivator-beam. Fig. 2 is a side view of my device,

with a portion of the `beam shown in dotted lines; and Fig. 3 is a sideview of the upper portion of the tooth-clamp with part of the beambroken away. y

A is a section of one of the beams of a cultivator. B is a clamp, havinga hub, B', cast with it, and hollowed out to receive the staple O frombelow, which straddles the hub B. The arms of staple U are then thrustinto openings in the beani,and,passing ont through the top, receive nutso upon their screw-threaded ends, by which the staple is tightened todraw the hub up into the concavity a in the beam, so as to lit ti ghtl ytherein.

I use the well-known reversihlestyle of tooth D, and this I secure tothe clamp by a strap,

(No model.) i

ofthe upper shvel when the tooth is in position. l

Operation Vhen the tooth is to he adjusted the nuts on the staple G areloosened. The clamp may then be turned in the direction of 4the lengt-hof the beam to secure the desired but not so great but that it would beovercome by meeting such anobstruction as a log or stone, in which case,instead of the tooth being broken or bent by resisting the obstruction,it will be merely thrown back from below, so as to point to the rear,and will slide over the obstruction, the hub B turning in bearingsformed by the beam above and the staple-hook below. After theobstruction has been passed the nuts may be turned so as to loosenstaple C, and the tooth can then be readjusted, to be secured again bytightening the nuts on the staple.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. A clamp for cultivator-teeth having hub B and ears b, in combinationwith a tooth, D, staple el, and securing-nuts.

2. A eultivator-beam having concavity a, in combination with clamphaving hub B', the staple C, and nuts, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this420th day of September, 1881.
